Because new substrates should arrive soon, we decided to pursue our investigation of the annealing of the AZTEC samples by taking several XY measurements with 1 mm step size (instead of 0.25 mm for the previous ones).

The results are reported in the attached entry where only z changes as : 45, 47 49 51 53 56 mm (same order as in picture).

Because of the large step size, it was not so obvious to draw conclusion on the improved/degraded homogeneity with annealing so we decided to start again measurements with 0.5 mm step size.

We are not so sure why the measurement at z = 45 mm (fig 1) has so many values at 0 ppm/cm (the surface should be around 41 mm)
